    * 03Apr13 AT incorporated changes below in class-based version
    *
    * 13Feb13 Eric Lee This report counts the number of transaction, not the
    *          number of, possibly unique, customers.
    *         Correct handling of date, memType, trans_num in various tables/views.
    *         Get member Type headings from table, except for "WFC"
    *         Add a report heading.
    *         Change WHERE trans_type from "in ('I','D')" to "= 'T'" because card_no,
    *          which is needed to derive memType is always available there but
    *          sometimes not for I and D items. Day and Grand totals are the same
    *          but member type counts more accurate with T.
